## Description

Build your own adorable robotic pet Hedgehog! With the 172 building pieces in this kit, you can assemble a real robot that looks like a cute Hedgehog. The robot has a built-in sound sensor and is programmed to react to different sounds. After you build it, you can play with it by making different sounds and watching it tumble, roll, spin around, Bristle its spines, and scurry around. Clap once, and the Hedgehog will roll into a ball and tumble backwards. Clap multiple times, and the Hedgehog will count your claps and tumble as many times as you instructed with your claps. You can also get the Hedgehog to Bristle its spines and act in a playful way with different patterns of claps. The Hedgehog eyes light up with LEDs. By building the robot, you will gain experience in the inner mechanical workings that enable the robot to move how it does. Learn about gears, motors, sound sensors, LEDs, and the other components of these funny little pet. Approximate build time: 1 to 2 hours. Difficulty level: challenging.

Review: Fun project! - Took about 2 hours to build with Mom and 8yo. Was kind of fiddly but we had built other T&K kits before and knew to expect this. The toy works just as advertised! In the green mode it flips for each clap, the orange mode you have to applaude like crazy, and in the green/orange mode he has an attitude and goes to sleep when he's bored. Pretty cute little build project!

### ⭐ A frustrating piece of junk.
*by M***R on December 30, 2020*

I'm good at assembly. I'm good at following printed directions - even mediocre ones that require a magnifying glass like the ones supplied with this kit. I cannot debug this thing. I've taken it apart and reassembled it several times, and the mechanism still clicks and binds every single time. The "modes" are difficult to find - you have to hold a button down for a short period of time, or a long period time - who knows - it's really hard to find the mode you want, and the damn thing takes forever to switch off. The motor wires break off and have to be re-soldered. Definitely not for a 7 year old, a 10 year old, or even a 50 year old. It's a poor design that is seems to be made complicated simply for the purpose of making it complicated... and for raising your blood pressure. One star and NOT recommended.
